Abstract

Vacuum drying is a widely used method for producing goat milk kefir powder. This technique removes moisture from fermented kefir while preserving its nutritional and probiotic properties. The production of goat milk kefir powder through vacuum drying providing an effective method to maintaining these qualities and extending shelf life. This study investigates the effects of adding dextrin, inulin, and egg albumin to improve vacuum-dried goat milk kefir’s physicochemical and microbiological properties. A completely randomized design (CRD) was employed, involving four treatments: P0 (control), T1 (2% Dextrin + 2% Inulin + 3% Albumin), T2 (4% Dextrin + 4% Inulin + 6% Albumin), and T3 (6% Dextrin + 6% Inulin + 9% Albumin), each with four replicates. Key parameters analysed included pH, dissolved protein content, total plate count (TPC), and colour. The results indicated that including dextrin, inulin, and albumin significantly improved protein solubility, enhanced probiotic viability, and stabilised the product’s colour. Treatment T1 (2% Dextrin, 2% Inulin, 3% Albumin) yielded the most favourable outcomes. This suggests that these additives are crucial in optimising the quality and functionality of vacuum-dried kefir powder. Overall, this study presents a promising method for enhancing kefir powder for commercial use, ensuring nutritional and sensory quality retention.
